Live Fault Finding #15 - Faulty Hall Effect Sensor 

Another good video, thanks for taking the time to do them. They are very helpful 👍

Good stuff mate

Subbed! Great content!

Great, thanks mate.

i have a unusual fault , my boiler works fine all day and night , no fault code or problems lighting or running , except the first time in the morning , when i run the hot water tap , which works correctly until i shut off the tap , then there is a high pitch whistling sound . if i flush the toilet it stops , i thought it may be at night the water main pressure is climbing up to a higher level, or the water flow turbine may need to be replaced, have you ever come across this problem.

Nice one

Good video. What type of heating system is this? Thanks.

Is that common with all boilers or just ideal boilers where rain water can run down the flue and into the boiler
